On a command with multiline quoted string like
begin
echo "line1
line2"
end
we actually indent line2 which seeems misleading because the indentation
changes the behavior when typed into a script.
This has become more prominent since commits
- a37629f86 (fish_clipboard_copy: indent multiline commands, 2024-04-13)
- 611a0572b (builtins type/functions: indent interactively-defined functions, 2024-04-12)
- 222673f33 (edit_command_buffer: send indented commandline to editor, 2024-04-12)
which add indentation to an exported commandline.
Never indent quoted strings, to make sure the rendering matches the semantics.
Note that we do need to indent the opening quote which is fine because
it's on the same line.
While at it, indent command substitutions recursively. That feature should
also be added to fish_indent's formatting mode (which is the default).
Fortunately the formatting mode already works fine with quoted strings;
it does not indent them. Not sure how that's done and whether indentation
can use the same logic.
